Answer:
49×66+49×34 = 49× (66+34)
60 minutes=1 hour
360 minutes=6 hours
so 360 minutes/90 minutes
so your answer is 4 hours
Answer:
x = 40°
Step-by-step explanation:
Two sides are the same length, so the angles opposite them are the same size.
The sum of the angles = 180°. One angle is 100°, so the sum of the remaining two angles is 80°.
Since the remaining two angles are congruent, each is 40°.
The trig function "sin" represents the opposite side / the hypotenuse. Therefore, sinC = c/a
Answer: D
Explanation: I am not completely sure but the angles would be the same because they are right next to eachother
Hope this helps ;)
